ADJUSTAB LE SHINGLING-GA GE Application filed April 6, 1908.

Specification of Letters Patent.

useful Improvements in Adjustable Shingling-Gages and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention relates to gages for roofing shingles and moreparticularly to the class of adjustable shingling gages adapted tofaoilitate the proper positioning of shingles when affixing the same toform a roof structure.

The primary object of the invention is the provision of a shingling gagehaving a straight edge member with adjustable locking clamps mounted atopposite extremities of said member and adapted for engagement withpreviously laid shingles to maintain the straight edge member as a gageto position the unlaid shingles in proper assembled relation withrespect to the laid shingles so as to form the roof structure.

Another object of the invention is the provision of a gage for arlixingshingles to form a roof and having a straight edge member adjustablyconnected with looking clamp elements carried at opposite ends thereofso "that the straight edge member can be adjusted without releasing thelocking clamp element when in operative position upon the fixed.shingles, and thereby properly position the shingles being laid insuperimposed relation to the said fixed shingles in the formation of theroof structure.

With these and other objects in view the invention consists in theconstruction, combination and arrangement of parts which will be morefully hereinafter described and as illustrated in the accompanyingdrawings forming part of this specification, and which disclose thepreferred embodiment of the invention, however, changes, variations, andmodifications will be made such as come properly within the scope of theclaims hereunto appended without departing from the spirit of theinvention.

In the drawings: Figure 1 is a perspective view of one end portion ofthe shingling gage. Fig. 2 is a longitudinal sectional view thereof.Fig. 3 is an end view of the straight edge member having the lockingclam) element detached therefrom. Fig. 4 is a sic e view of the lockingclam element. Fig. 5 is a re verse side view oi the same.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings. 1

In the drawings there is shown one end portion of a straight edge member1O which may be of any desirable length and width, and in this 'nstanceis constructed of wood, though it can be of any other material should itbe deemed desirable. The straight edge member 10 has at opposite endedges plates 11 however, only one is shown secured there to byfastenings 12 and each having an out wardly projecting threaded stem orlug 13 for slidably connecting locking clamp members 14 to said plates.

The locking clamp members 14 each comprise an elongated plate having inits inner face a longitudinal recess 15 into which slidably engages theplate 11 and said recess is intersected for a portion of itslongitudinal extent by an elongated slot 16 through which passes thethreaded stem 13 carrying an adjustable nut 17 having its bearingagainst the outer face of the plate. The end of each recess 15 is closedby an abutment wall 18 to limit the sliding movement of the straightedge member 10 in one direction when the latter is being adjusted withrespect to the locking clamp members.

Each abutment wall 18 has an extension 19 at right angles to the plateand terminates in a tapering jaw 20 s aced a distance from the latterand paralle with its lower edge. The inner face of the tapering jaw 20has a plurality of biting teeth 21 to form an antislipping surface, forengagement with a roof shingle. Upon the outer face of each plate of thelocking member 14 is a clamping lever 22 having an enlarged camextremity 23 pivoted as at 24 to said plate, and which cam extremity isprovided with a plurality of projecting teeth 25 for biting engagementwith a roof shingle.

In operation when it is desired to lay the roof shingles to form theroof it is first necessary to aflix a row of shingles at the caves andafter this has been done the locking clamp members 14 are positioned soas to have the tapering jaws engage under the lower faces of the laidshingles at their thicker lower ends so as to have the same abut againstthe extensions 19 and in this position the plates of the locking clampmembers will overlie the upper faces of the row of shingles.

iposed above the straight edge member 10 securing them in place.However, prior to the securing of the shingles, should the roofer findthe shingles being laid not properly positioned, he may then loosen thenut 17 on the stems 1 3 and properly adjust the straight edge member bysliding the same along the recesses 15 in the inner faces of theelongated lates of the locking clamp members 14.

Then correct adjustment of the straight edge member 10 has been attainedthe nuts 17 must again be tightened. This operation is successivelycontinued until the entire roof structure has been completed.

What is claimed'is 1. In a'shingle gage, a straight edge member, platescarried at' the opposite ends thereof, outwardly projecting threadedstems on said lates, locking clamp members com-- ed stems, and nutscarried by the stems for holding the locking clamp members inair justedpositions.

2. In a shingle gage, a straight edge member, plates fixed to theopposite ends thereof, longitudinally recessed plates slidably" ena g Snd P a e edessedr et having a right angular extension term nating intapering toothed jaws, toothed cam levers pivotally connected to theouterfaces of the recessed plate and cooperative with the jaws, a meeholding th e s ed pla e n. adjusted position with respect to thestraight edge member. z

\ In testimony whereof, I affix my signature, in presence of twowitnesses. v i IAM H. SM THEBS- nesses i RED LL R ORE' MILLER.
